AC Installation Process

Here's How We Handle Your Installation

First, we calculate your home’s actual cooling load. Square footage alone doesn’t tell the whole story—we factor in insulation, windows, sun exposure, and how your home sits relative to prevailing winds off the water.

Next, we walk through equipment options that match your calculated needs and budget. No overselling, no pushing the most expensive unit. We provide honest recommendations based on what will effectively fit into your space.

Installation day involves careful attention to refrigerant lines, electrical connections, and ductwork modifications if needed. We test everything thoroughly before we leave. You’ll know exactly how to operate your new system and what to expect for maintenance.

The job isn’t finished until you’re completely satisfied with the cooling performance and understand your warranty coverage.

Complete AC Replacement Services

What's Included in Your Installation

Every air conditioning installation includes proper load calculations, professional equipment sizing, and complete system testing. We handle electrical connections, refrigerant line installation, and any necessary ductwork modifications.

You receive manufacturer warranties on equipment plus our labor warranty on installation work. We also provide clear operating instructions and maintenance recommendations to protect your investment.

For Fairhaven homes, we pay special attention to coastal air considerations and humidity control. Many local installations fail because contractors don’t account for how salt air and high humidity affect system performance over time.

We clean up completely and dispose of old equipment responsibly. You’re left with reliable cooling and peace of mind, not a mess to deal with.

Most residential AC installations take 6-8 hours for a complete system replacement. This includes removing the old unit, installing new equipment, connecting refrigerant lines, handling electrical work, and thorough testing. Homes requiring ductwork modifications or electrical upgrades may take longer. We’ll give you a realistic timeline upfront so you can plan accordingly. Our goal is completing quality work efficiently, not rushing through the job to get to the next appointment.
Proper sizing requires a detailed load calculation that considers your home’s square footage, insulation levels, window placement, and local climate factors. Fairhaven’s coastal location means higher humidity levels that affect cooling requirements. Many contractors guess based on square footage alone, leading to oversized units that short cycle and waste energy, or undersized units that can’t keep up. We perform Manual J load calculations to determine the exact capacity your home needs for efficient, reliable cooling.
Yes, we handle all necessary permits and coordinate required inspections for your AC installation. Fairhaven requires permits for most HVAC installations, especially when electrical work is involved. We’re familiar with local requirements and maintain good relationships with local inspectors. This saves you time and creates your installation meets all code requirements. You don’t need to worry about paperwork or scheduling—we handle those details as part of our service.
If your newly installed system isn’t performing as expected, we return immediately to diagnose and correct the issue at no charge. Our installation warranty covers both equipment and labor, so you’re protected if something isn’t working right. Most cooling issues after installation stem from sizing problems or installation errors – both preventable with proper planning and execution. We stand behind our work completely because we want you satisfied with your investment for years to come.
Absolutely. Many older Fairhaven homes were built before central air became standard. We install ductwork systems designed specifically for older home layouts, working around existing plumbing, wiring, and structural elements. Ductless mini-split systems are also excellent options for homes where traditional ductwork isn’t practical. We’ll evaluate your specific situation and recommend the most effective, least disruptive approach for adding central air conditioning to your home.
AC replacement involves removing an existing system and installing new equipment, typically using existing electrical and refrigerant line connections. New installation means adding air conditioning to a home that never had it, requiring complete electrical work, ductwork installation, and sometimes electrical panel upgrades. Replacement is generally faster and less expensive since infrastructure already exists. New installations take more time and planning but give you a completely fresh system designed specifically for your home’s current needs and layout.
